SAW-HANDLE.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed September 19, 1905. Serial No 279,185.

To all whom it may concern:

. Be it known that I, OSCAR F. MoKINNEY, a citizen of the United States, residing at Montesano, in the county of Chehalis and State of Washington, have invented a new and useful Saw-Handle, of which the following is a speciiication.

This invention relates to the handle of saws, more particularly to crosscut-s'aws of after fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation.

In the drawings thus employed, Figure 1 is a side elevation, and Fig. 2 is front elevation, of the improved device. Fig. 3 is a sectional detail on the line 3 3 of Fig. 1. Fig. 4 is a detached perspective view of the clam -nut.

The improved device comprises a ead portion 10, having spaced arms 11 12 extending from one side and terminating in sockets 13 14 for receiving the handle or grip portion 15 of the device, the latter being preferably of wood. The socket 14 is smaller than the socket 13, and the handle member 15 is reduced where it passes the socket 14, whereby a shoulder 16 is formed to support the handle and prevent it from passing entirely through the sockets. The arm 12 is spaced from one end of the head members 10, as at 17, thereby forming a hand-guard at one end of the same. Formed in the face of the head member 10 opposite to the arms 11 12 is a channel 18 for receiving the end of the saw, (represented at 19,) the channel extending the whole length of the head member, but not extending entirely through the same, as shown. Projecting from the channel side of the head member and intermediately of the arms 11 12 are lugs 20 21, one at each side of the channel and diverging toward their free ends or with their outer ends thickest and provided with transverse slots 22 23, disposed at right angles to the longitudinal plane of the head member. Operating through the slots 22 23 is a clamp-bolt 24, having a head -25 at one end provided with wings 26 and bearing upon a washer 27, which in turn bears upon one of the lugs 20 or 21, and with a nut 28, preferably of the blind form, upon the other or threaded end and bearing upon the other lug 20 or 21, as the case maybe. The saw 19 is perforated, as at 29, to receive the clamp-bolt.

By this simple arrangement it will be obvious that the saw may be tightly pinched between the lugs 20 21 and firmly held thereby, and if the clam -bolt is disposed at or near the inner ends 0 the slots 22 23 the outward longitudinal strains upon the saw which will be produced when the same is operated in the act of sawing will draw the head 25 and nut 28 of the bolt 24 along the diverging surfaces of the lugs, and thus materially increase the grip upon the saw at the outer ends of the lugs and relieve the bolt in some measure of shearing strains. The pinching of the saw thus produced also efiectually prevents wabbling or lateral looseness, and the greater the strains applied longitudinally to the saw the more tightly will the same be held.

The nut 28 is formed with shoulders 30, bearing upon the sides of the slot 22 or 23 adjacent to which it is located, and thus prevents the rotation of the nut upon the bolt, the latter, as it will be observed, being rotatable in the nut.

The device is readily adaptable to any of the various forms and sizes of crosscut-saws used in lumbering operations, such as buckers, fallers, and the like, without material structural change, and any size of saws of this character may be supported therein and operated from any position.

By arranging the gripping-lugs 20 21 intermediately of the arms 11 12 the pull of the operator is in longitudinal alinement with the center of the saw, thereby producing the best results and minimizing the tendency to laterallvibrations or wabbling when being operate Having thus described the invention, what is claimed is- In a saw-handle, a head portion having spaced arms extending from one side and terminating in sockets for supporting a handle.

member and with a saw-receiving channel in the other side spaced lugs extending from the channel side of said head and at opposite sides of the same and provided with transverse slots at right angles to the longitudinal plane of the head, the outer faces of said lugs diverging from the head portion, and a bolt operating through said slots and the saw disposed in said channel and between said lugs and provided with a head at one end and a nut upon the other end for respectively bearing upon the diverging faces of said lugs, whereby the longitudinal strain upon the saw increases the grip of the handle structure IO upon the same.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
